This one is better known:
It was in Bihar and is now in Jharkhand. It is on the way from Chandil to Muri. A number of express trains pass this way, but only two pairs of passenger trains stop here-one between Tatanagar and Hatia and another between Tatanagar and Barkakana.
(While most stations in Bihar have Urdu script in their signs, this is not true in Jharkhand)
This one in Karnataka is nominally a junction, but has fallen on bad days. In fact it is no longer listed in the IR databases such as the RBS tables.
You can see the branching of lines in these pictures. This station is on a branch running south from Hosapete (formerly Hospet). At this junction (which must qualify as one of the smallest and most rudimentary stations with the title of junction) short lines ran to Kotturu and Swamihalli. There used to be heavy iron ore traffic on the then metre gauge line from Swamihalli.
In due course these lines were converted to broad gauge. From Kotturu a new BG line was extended to Harihar, near Hubli on the Pune-Bengaluru route. It was then discovered that the slopes on the BG line between Gunda Road and Kotturu were too steep for safe running, so no train ran there for a long time. In 2023, the line from Kotturu to Harihar has two pairs of trains a day. Goods trains appear to run from Hosapete to Swamihalli though there seems to be a bypass around Gunda Road. No passenger service runs on this line.
By mid-2019, Gunda Road does not appear in the RBS tables. Instead, there is a new junction station called Vyasa Colony a few km to the north.
Then there are place names such as Ramagundam.
I don’t know about the etymology of the place in Jharkhand, but “Gundam” is a body of water in languages such as Kannada and Telugu. This would not have anything to do with the Japanese animes of the same name. And Karnataka had a CM called Gundu Rao.
